Rear part of ship

Answer 1

The aft part of a ship is the stern. Remember, the bow is the pointy end and the stern is the flat end (usually).
The rear is the stern. To go towards the rear is to go aft. The bulkhead furthest aft is called the transom (very important to have because of all the water on the other side of it). If something lies further aft than another thing it is abaft that other thing. If you are abaft the stern, you are astern or wet.
The rear part of a ship is called the stern.

The actual flat part (if there is one) is called a transom. Canoes and kayaks don't have one, row boats generally do.

The rear direction is called aft.

To steer the ship to aft (turn 180º) is called full about.

If you are moving from the bow to the stern, you are moving abaft.
"The Stern" is the rear portion of a ship.

Other terms include, but ARE NOT LIMITED to, abaft and astern.
If you're talking about the rear in terms or area or direction, then it's "aft." If you're talking about the structural rear, then maybe the term you're looking for is either "stern" or "transom." More generally the stern is the area, and aft is it's direction. For instance if you were at the front of the ship (the bow) you could walk aft to the stern.
The STERN or FANTAIL. On the old wooden ships like the early settlers rode over it was often called the "poop deck" for a very obvious reason. The front of the ship is called the Bow. Pronounced like ow I hurt my hand.
